Materials Acceptance by Certification

Introduction

All materials shall be inspected and/or tested, and accepted by the Engineer before incorporation into the work.

Frequently, materials are used in constructing a project which are fabricated or manufactured at plants or locations far

removed from the project. The quantities involved may not warrant sending a project inspector to the plants to sample, test

or otherwise inspect the material. In these cases the material may either be accepted by a Certificate of Guarantee (Fig. 1)prepared by the supplier and based on tests by or for him, or samples can be taken and tested after the material arrives on the

project. The second option is restricted for many items as the tests involved may be very specialized and beyond the

capabilities of the laboratory facilities available to the Engineer. Special arrangements may be required when these materials

are specified on a project.

Even though a Certificate of Guarantee is available for a product and it is recognized as the primary basis for acceptance of

the product, it must also be recognized that final acceptance is in the hands of the Engineer. To that end, a visual check of

all materials received on a project must be made to verify that no discernible damage has occurred in shipment or that no

visible flaws were missed in prior inspections.

Those items of major importance which are used in normal highway construction and may fall in the category discussed

above are:

1. Portland Cement

2. Asphalt Materials

3. Reinforcing Steel

4. Structural Steel

5. Precast Concrete Pipe

6. Miscellaneous Metal Products

7. Lime

Methods for documenting that only those materials meeting the required specifications are incorporated into the work are

described individually in the following sections.

Certification of Portland Cement

A. Introduction

Portland cement is the finely pulverized product resulting from the calcination and subsequent grinding of an artificial

mixture of properly proportioned argillaceous and calcareous materials. It has definite chemical composition varying within

comparatively narrow limits. The physical properties of strength development, setting time and workability are related not

only to the chemical composition but also to the fineness of grind of the cement.

Portland cement as it is manufactured is generally identified by storage silo or bin and date. As the silo or bin is being filled,

routine samples are taken and when tested constitute a Mill Test Analysis for that silo or bin. All shipments from storage,

whether by bulk or sacks are to be identified as coming from a particular silo or bin and certified Mill Test reports are to

accompany the shipment. See Fig. 1. for an example of a certified notice of cement shipment and Fig. 2. for a typical mill

analysis.

B. On-Site Inspection

As each shipment of portland cement is received at the job site, the Inspector shall verify that the shipment is identified with

a specific silo or bin of cement and that certified Mill Test Analyses have been received for all material in the shipment.

Check the cement for any hard lumps. Any cement that has been stored on the job for more than three months should be

checked very carefully and retested before permitting its use if there is any evidence of caking or improper storage. Be sure

that only the type of cement specified for any particular segment of work is used. Sample each shipment according to theSampling and Testing Frequency Guide of Part I of this manual.

Certification of Asphalt Materials

A. Introduction

Asphalt materials normally used in highway construction are of three basic types:

1. Asphalt cement, or paving asphalt,

2. Liquid, or cut-back, asphalts, and

3. Asphalt emulsions.Asphalt cement is also known as penetration grade asphalt with the various grades identified or classified according to

penetration obtained when tested in accordance with MRDTM 404 with the lower the penetration, the harder the asphalt.

Liquid asphalts are composed of base asphalt cements which are diluted, or cutback with various petroleum solvents. They

are identified first by the type of solvent used arid secondly by viscosity of the liquid asphalt as determined when tested

according to MRDTM 421. If a naptha or gasoline type solvent is used the liquid asphalt is identified as an RC grade arid if

a kerosene type solvent is used, the liquid asphalt is an MC grade. There is also an SC grade available, but it is not presently

used in Saudi Arabia and has very limited use elsewhere.

Emulsified asphalts are emulsions of asphalt cement in water with a small amount of an emulsifying agent and stabilizer.

The two primary types of emulsions are anionic and cationic with electro-positively charged asphalt particles. In each type

there are a number of grades which vary in their viscosity and setting times.

During the normal production of asphalt materials, the refinery will blend the basic stock with the required cutter stocks or

blending oils to produce the type and grade of asphalt material desired. When blended the material is then placed in storage

tanks according to type and grade. During placement routine test samples are taken for quality control and to insure

compliance with specification requirements. Based on these quality control tests, the producer is able to certify that asphalt

materials supplied by him will conform to the specifications for the type of material desired. Accompanying each shipment

should be a certificate of compliance similar to that shown in Fig. 1. The results of the quality control tests upon which the

certification of compliance is based shall be available at the request of the Engineer.


There are many types and grades of asphalt materials available and it is important that the materials received on a project be

those ordered or required for the work being done. A certificate of compliance must accompany each shipment and must bechecked for type and grade. When the shipment is received on the project be sure that it is placed in the proper on-site

storage according to type and grade. This is important not only to insure against contamination but also from a safety stand-

point. Contamination should be guarded against as much as possible. The same tanker trucks are frequently used to haul

consecutive loads of different materials and must be completely emptied after each delivery to prevent contamination of the

next load. In a similar manner, it is common to use diesel oil or other solvent for cleaning and flushing of tanks, lines and

pumps after discharging the asphalt materials. Any solvent used in this operation must be removed before loading the next

material. Only a few liters of solvent contaminating a tank full of asphalt can adversely affect the properties of that asphalt.

Sample asphalt materials in accordance with the Sampling and Testing Frequency Guide of Part I of this manual.

Reinforcing Steel

A. Introduction

It is necessary that a chain of identification be developed for reinforcing steel in order that individual pieces of steel as

placed in the structure may be traced back to the heat of steel as rolled and tested by the rolling mill. In order to accomplish

this, the steel fabricator furnishing reinforcing steel must accompany each shipment of steel to the project with a certificate

which includes the following information:

Name and location of the steel rolling mill,Manufacturing process,

Heat number(s),

Size(s),

Specification,

Copies of mill test analyses for chemical and physical tests,

and

Consignee and destination of shipment.

An example of reinforcing steel certification is shown in Fig. 1. and a typical Mill Test Analysis is shown in Fig. 2.


Upon arrival of a shipment of reinforcing steel on the job site the Inspector shall review the Reinforcing Steel Certification,Mill Test Analysis and other Shipping documents accompanying the shipment to insure that all the steel as placed in the

structure meets the specifications and can be identified by Heat Number. Check the steel for excessive rust or mill scale and

pitting or surface defects. Surface rust or mill scale are acceptable provided the unit mass of the bar does not drop below the

specified value when the rust and mill scale are removed by hand brushing with a wire brush and further provided that when

the rust is removed there is no evidence of pitting into the metal. Also to be checked for is evidence of rough or careless

handling which resulted in serious nicks in the surface of the bar. The yield strength of a bar is significantly reduced at the

location of any surface irregularity put into the bar after cooling from the rolling process. Sample reinforcing steel according

to the Sampling and Testing Frequency Guide of Part I of this manual.

Certification of Structural Steel

A. Introduction

It is necessary that a chain of identification be developed for all structural steel in order that the individual segments of steel

as they exist in the structure can be identified from the time of manufacture at the steel mill. This identification is through

heat numbers as translated to the various piece numbers as fabricated. In order to accomplish this, each shipment of steel as

received on the project must have each piece of structural steel marked and be accompanied by a tally sheet or fabrication

worksheet which identifies the individual segments and also includes the heat number information for the steel from whichthe segments were fabricated. There must also be copies of the mill test analysis for each heat involved and should include

both the chemical laddle analysis and the physical test results including the Charpy impact test results when specified. A

typical mill test report is shown in Fig. 1.


Upon receipt of a shipment of structural steel at the project site the Inspector shall review all documents related to the

shipment to insure that the Ministry has in hand all necessary mill test analyses, fabrication worksheets and shipping

documents as needed to identify the individual segments of the steel to the heat numbers as originally rolled and tested by

the manufacturer. If off-site fabrication and inspection is involved, be sure all material is tagged or identified to verify the

inspection and acceptance for the steel as received. Any items that have been painted should be checked for damage to the

paint film and any damage repaired before accepting the steel. On unpainted steel, look for excessive rusting that would

include pitting. If welds are visible on any of the work, check for uneven sloppy welds or badly discolored steel surroundingthe welded area which would indicate uneven overheating of the metal during welding or improper preheating or post

heating of the weld area. Be especially alert for any cracks in or around the welds and be sure proper corrective measures

are taken before the steel is installed. Inspectors and Engineers should be particularly alert whenever intersecting welds are

noted on fabricated members. This is a design detail which the Ministry of Communications is attempting to eliminate as it

has been found by experience to be undesirable. Any such members containing intersecting welds should be brought to the

immediate attention of the Engineer and the Ministry of Communications.

Structural steel items are not normally sampled when the procedures discussed above are followed. However, if

identification of any piece of steel cannot be determined, samples may be cut from the specimen if practical.

Certification of Miscellaneous Metal Products

A. Introduction

There are a number of fabricated metal products that are routinely used in roadway construction other than those covered

previously. Among the more common are guardrail, corrugated metal pipe, steel piling, catch basins, and sign materials.

Each of these materials are required to meet certain specifications which usually include quality levels in both the basic

metals used and the fabrication of the completed product. Just as in reinforcing and structural steel, it is necessary that the

basic materials in any fabricated products be identified from the time of rolling or casting at the mill. This continuity of identification can be maintained through heat, casting, or lot numbers with certified test results for each. All shipping or

other control documents must include the heat, casting or lot number and be accompanied by certified test reports for the

materials involved. Typical test report forms are shown in Fig. 1 and Fig. 2.


As shipments of manufactured metal products are received oil the project, the Engineer must confirm that all materials are

properly identified and that inspection or test reports are available. If offisite inspection has been done by representatives of

the Ministry, the material as received must be clearly marked or tagged in a recognized manner. Look for evidence of any

damage during shipping or handling and reject those items which cannot be satisfactorily repaired. Things to look for

include: scratches ill coatings of paint or galvanizing, cracked or chipped castings, bent or otherwise distorted rails or

shapes, and excess mill scale or rusting and pitting of steel. Check bituminous coated metal pipe for coating according to

the job specifications. Look for cracks in the bituminous coating and require repairs where found. Field samples for thesematerials are not routinely taken.

Certification of Lime

A. Introduction

Lime used in mortar for masonry work may be either of two types known as hydrated lime or quicklime. Hydrated lime

when received on the project will be in bags of fine powder similar to portland cement whereas quicklime may be in the

form of chunks or pellets. Quicklime, when used, must be mixed with water at least 72 h before using and kept moist until

used. Hydrated lime is to be used immediately after mixing with water. Both types have definite chemical composition

requirements; however, the physical requirements for hydrated lime include fineness, setting time, soundness andcompressive strength while the only physical requirement for quicklime is a minimum plasticity value. A mill test report that

is applicable for either lime type is shown in Fig. 1.


As shipments of lime are received on the Project, the Engineer must be sure the material is properly identified and that mill

test analyses representing the material are available. Lime must be stored in weather-tight facilities to protect the material

from damage. If it is quicklime, the material must be slaked according to the manufacturer's recommendation, allowing the

required setting time before use.

Standardization of Project Laboratories

A. Introduction

While it has been said that one test is worth a thousand opinions, there is a corollary that must be recognized. That

is, an erroneous test is worse than no test at all. Two principal sources of error in a test are faulty equipment and faulty

procedure.

Faulty equipment is given first priority for, while most testing errors will be the result of faulty procedure, there will

always be erroneous results when faulty equipment is used no matter how correct the procedure. Therefore the firstrequirement in standardization of project laboratories is a review and standardization of all equipment being used.

After equipment has been calibrated and otherwise verified, test procedures are to be observed and any noted errors

corrected.

B. Test Equipment Standardization and Calibration

Inspectors responsible for measuring and calibrating test equipment in all project laboratories as well as all MOC

laboratories shall be equipped with calipers, standard weights, proving rings and all other precise measuring devices as

needed. The following report sheets will be used to record the results of the equipment review. The report sheets are

arranged in the same order as the sections of the Materials Manual. Only those report sheets or parts of report sheets which

are applicable to the tests and equipment under review need be used. However, those parts not used should be marked N/A

(not applicable) or otherwise indicated when not filled out.

C. Test Procedure Review

The second requirement in the standardization of project laboratories is the review of test procedures or methods in

each laboratory. This is to be done in conjunction with the equipment standardization and calibration, and a set of

questionnaire sheets is provided to guide the inspector through the various test procedures. These questionnaires are not

intended to cover every operation in a test, but do concentrate on those steps which experience has shown to be the most

frequent sources of procedural error.

As with the report sheets for equipment calibration, the questionnaire sheets are arranged in the same sequence as

the sections of the Materials Manual. Also, it is expected that all sheets in a section will either be filled out or information

given that the questions do not apply.
