properties, gradation and asphalt cement content. Costs for the trial plant mixes and laboratory testing are at the contractor’s expense. Warm Mix Asphalt, as outlined in OPSS 310 - Appendix C, is required when the minimum ambient temperature conditions for paving set out in Section 12.2 of this specification, are not satisfied.

Mixture Based on Road Performance Gradation Types of

In order to evaluate the shear performance of asphalt mixtures with different gradation types, two kinds of substances, glycerol and asphalt, were used as the media of mixture for triaxle test. The test results show that the shear performance of the mixture is greatly influenced by the gradation of the mixture.



SEGREGATION: Causes and Cures

size that retains material. The gradation along this line will be the densest mix that can be produced. Experience dictates that mixes with gradations that fall directly on the maximum density line should not be produced. Since there is insuf˜cient room in the mixture for the liquid asphalt, a very dry mix results. It

Sieve analysis

A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.

resilient modulus. Testing was also conducted on reclaimed asphalt pavement (RAP) and reclaimed concrete aggregate (RCA) to evaluate their potential use as base and subbase materials. The testing of the RAP, RCA, and their blends with the base material, showed that as the % RAP increased in the blend, both the CBR value and permeability decreased.

Reviewing asphalt test results

GRADATION. The purpose of requiring a gradation on field samples is to help ensure that the asphalt plant used the same aggregates as reported on the asphalt mix design, in the same proportions. The gradation of all of the aggregates mixed together, plus the design binder content is called the job mix formula (JMF).
