Effect of aggregate types on the performance of neat and

The physical and mechanical properties of EVA-modified bitumen and neat bitumen aggregate mixes were evaluated. Moisture susceptibility tests and wheel tracking test were carried out on the samples. Brookfield viscometer and dynamic shear rheometer were used to determine the mixing and compacting temperatures of neat and modified bitumen.

Polymer Modification of Paving Asphalt Binders | Rubber

The most significant of these, based on microscopy, are the asphalt crude source, polymer microstructure and the thermal/mechanical history of the polymer-modified asphalt binder. • Classical methods and methods derived specifically for measuring the effect of polymers in the asphalt have poor correlation to mixture performance.

7 MUST HAVE PROPERTIES OF ASPHALT CONCRETE

The durability of an asphalt pavement is its ability to resist factors such as changes in the binder (polymerization and oxidation), disintegration of the aggregate, and stripping of the binder films from the aggregate. These factors can be the result of weather, traffic, or a combination of the two. Generally, durability of a mixture can be

Mechanical Performance of Asphalt Mixture Containing Cup

The use of cup lump rubber as an additive in asphalt binder has recently become the main interest of the paving industry. The innovation helps to increase the natural rubber consumption and stabilize the rubber price. This study evaluates the mechanical performance of cup lump rubber modified asphalt (CMA) mixture in terms of resilient modulus, dynamic creep and indirect tensile strength under

Characteristics of Asphalt Mixed Using Mountain Stone

It can be seen that water immersion greatly affects the stiffness modulus of the asphalt mixture. This stiffness will cause the asphalt mixture to be easily damaged or cracked. This can be caused by the influence of the sub-standard aggregates used, namely Senoni stone and Mahakam sand. Doi: 10.28991/cej-2021-03091652.
