The objective of this study was to evaluate selected ODOT mixtures to assist with determining test procedures, specifications and special provisions for evaluation and eventual adaptation of a BMD procedure for ODOT.

MARSHALL MIX DESIGN PROJECT - KSU

OBJECTIVES OF ASPHALT PAVING MIX DESIGN The design of asphalt paving mixes is largely a matter of selecting and proportioning materials to obtain the desired properties in the finished construction. The overall objective of the design of asphalt paving mixes is to determine an economical blend and gradation of aggregates and asphalt that yields ...

Mix Design – Pavement Interactive

The goal of mix design is to determine the optimum mixture of component materials for a given application. This includes detailed evaluations of aggregate, asphalt and portland cement as well as a determination of their optimum blending ratios. This section covers the following for HMA and PCC mix design: Mix design fundamentals.

Warm Mix Asphalt Technologies and Research - WMA - Sustainability ...

The National Cooperative Highway Research Program (NCHRP) has approved research Project 09-43 "Mix Design Practices for Warm Mix Asphalt Technologies" for fiscal year 2007. The objective of this research project is to develop a performance based mix design procedure for warm mix asphalt in the form of a manual of practice.

History of asphalt mix design in North America, Part 2

Superpave mix design was developed as part of the Strategic Highway Research Program (SHRP) from 1987 to 1993. The objective of the Asphalt Research Program was to develop a performance-based asphalt binder specification, a performance-based asphalt mixture specification and a mix design system.

Chapter 11 MARSHALL METHOD OF ASPHALT-CONCRETE MIX DESIGN

8. Low noise and good drainage properties: If the mix is to be used for the surface (wearing) layer of the pavement structure. Marshall stability and Hveem stabilometer tests are largely used for the routine testing. Criteria for the suitable mix design have been specified by the Asphalt Institute. 11.2 OBJECTIVE To design the Asphalt concrete ...

PCC Mix Design Fundamentals – Pavement Interactive

This section covers mix design fundamentals common to all PCC mix design methods. First, two basic concepts (mix design as a simulation and weight-volume terms and relationships) are discussed to set a framework for subsequent discussion. Second, the variables that mix design may manipulate are presented. Third, the fundamental objectives of ...

Moving Towards Balanced Mix Design for Asphalt Mixtures - Auburn University

Today, asphalt mixtures are primarily designed under the Superpave system, where proportioning of the aggregates and the asphalt binder relies primarily on empirical aggregate quality characteristics and mixture volumetric properties such as air voids, voids in the mineral aggregate (VMA), and voids filled with asphalt (VFA).

Asphalt Concrete Mix Design - KSU

Marshall Mix Design • Select and test aggregate • Select and test asphalt cement – Establish mixing and compaction temperatures • Develop trial blends – Heat and mix asphalt cement and aggregates –Compact specimen (102 mm diameter) bit. = 4% 4.5% bit. = 5% bit. = 5.5% (Just an example) bit. = 6%

What is the principle of Asphalt Mix Design? - Civil Engineering Portal ...

The main objective of asphalt mix design is to achieve a mix with economical blending of aggregates with asphalt to achieve the following : (i) workability to facilitate easy placement of bituminous materials without experiencing segregation;

Evaluation of VMA and Film Thickness Requirements in Hot-Mix Asphalt
