EFFECT OF LOW DENSITY POLYETHYLENE AS BITUMEN MODIFIER ON

was investigated by studying its effects on some selected properties of Hot Mix Asphalt, such as, bulk density, stability and flow of the asphalt concrete mix. Specimen preparation was done using Marshall Mix design procedure. The optimum binder content was determined as 5.20% and three

1. Introduction

The optimum bitumen content value chosen is 5.1% ± 0.3%. d) Mix design with basalt granulate (F4) The mix design with basalt granulate shows these best performances in the range 5% - 6% binder content. The optimum value of the binder content chosen is 5.5% ± 0.5%. The results of these formulas are summarized in Table 7.

DETERMINATION OF OPTIMUM BITUMEN CONTENT IN MARSHALL MIX

This bitumen content is not necessarily the optimum bitumen content. In this paper a nonlinear programming model is developed to determine the optimum bitumen content from Marshal or modified Marshal Method. To do that, first of all the equations which relate the effective parameters in Hot Mix Asphalt Design such as density of mixture, Marshal ...

OPTIMUM BITUMEN CONTENT FOR BITUMINIOUS CONCRETE –

The major parameter in design of hot mix asphalt (HMA) widely used in flexible pavements as base course and surfacing course all over the world, is to find out the optimum bitumen content (OBC) required in achieving the desired objective. Bitumen is a costly

The Use of Polyethylene in Hot Asphalt Mixtures

optimum asphalt content was 5.4%. Seven proportions of polyethylene of each type and state by weight of the optimum binder content were selected to be tested (6, 8, 10, 12, 14, 16 and 18%). The tests include the determination of bulk density, stability and flow. Marshall mix design requires the

HMA Mix Design Fundamentals

HMA Mix Design Fundamentals HMA consists of two basic ingredients: aggregate and asphalt binder . HMA mix design is the process of determining what aggregate to use, what asphalt binder to use and what the optimum combination of these two ingredients ought to be.

compaction temperatures for hot mix asphalt design and construction with modified asphalt binders. It was found that application of the shear rate concept rather than the traditional approach used for unmodified binders can reduce the mixing and compaction temperatures between roughly 14 to 38 C for the former and 10 to 27 C for

Hot Mix Asphalts 101

Asphalt Rubber Applications • Asphalt rubber is the process of adding recycled, crumb rubber to hot mix asphalt (called dry process) or the asphalt binder (called wet process) to modify the final mixture • Difficult to use in dense-graded mixtures due to residual crumb rubber • Best used in gap-graded type mixtures (SMA and OGFC)

Optimum Bitumen Content - an overview

In brief, the test procedures involve heating, mixing and compacting the bituminous bound aggregate mix over a range of bitumen contents. The optimum bitumen content of the mix is selected based on a set of design parameter criteria for the mix including stability, flow, air voids, voids filled with bitumen (VFB) and voids in mineral aggregate ...

Selection of the design aggregate structure (design blend) consists of determining the aggregate stockpile proportions and corresponding combined gradations of the mix design. The design aggregate structure, when blended at the optimum asphalt binder content, should yield acceptable volumetric properties based on the established criteria.
