Innovations in Asphalt Mixture Design Procedures

PDF Chapter 2 Design and Control of Bituminous Mixtures Using

Using a Modified Marshall Design Procedure 1. General Scope The Department has established procedures for the design and control of bituminous concrete based on Marshall Method for more than 30 years. Since the late 1990's, the Department has established a goal of implementing a newer mix design method, referred to as Superpave;

Mixture Performance Testing - Asphalt Institute

The Asphalt Institute provides performance testing services that predict potential behavior of an asphalt mixture. This allows one mixture to be compared to another, or can be used to better understand how one variable can change the performance of a mixture. Accelerated Mixture Performance Test (AMPT) One of the newest tests to the asphalt industry

High-contact pressure Modified mix design Indirect tensile test Standard mix design 19. ABSTRACT (Continued).!Results indicated that current heavy-duty mix selection criteria can be used, but higher compactive effort is needed to prevent rutting and densification problems. Lower asphalt content mixes were selected when higher compactive efforts

Mixing and Compaction of Hot and Warm Asphalt Mixtures

May 01,  · The overall goal of selection of mixing and compaction temperatures in the mix design process is to determine the range of temperatures at which the mix can be constructed to achieve density and perform well in the field.Mixture performance is dictated by both asphalt binder properties and the quality of the aggregate structure developed during

Thus, all mix design methods use density and voids to determine basic characteristics of the asphalt mix (AASHTO TP4).Two different measures of densities are typically taken: (i) bulk specific gravity, G mb and (ii) theoretical maximum specific gravity, TMD. G mm and the test data are used to calculate the volumetric parameters of the asphalt mix. . Measured void expressions are typically (i

PDF Marshall parameters for quality control of hot mix asphalt

Marshall stability and flow of asphalt mixtures, along with field mixture density, VA, VMA and/or VFA, are used for bituminous mix design in laboratory and in-situ control. In addition, the Marshall parameters are very useful for controlling the plant production process of asphalt mixtures (ASTM D6927).
