Evaluation of the properties and microstructure of SBS and EVA polymer modified bitumen.
September 1, 2008... Abstract This paper presents a laboratory study of modified bitumen containing styrene-butadiene-styrene (SBS) and ethylene vinyl acetate (EVA) copolymers. The polymer modified bitumen (PMB) samples have been prepared by means of multi...

Recycling of laboratory-prepared long-term aged binders containing crumb rubber modifier.
September 1, 2008... Abstract The use of conventional reclaimed asphalt pavement (RAP) has become routine in a number of states throughout the United States, and the satisfactory mix design procedures have been developed. The recycling of crumb rubber-modified...

Slag-cement mortar made with cement and slag vitrified from MSWI fly-ash/scrubber-ash and glass frit.
September 1, 2008... Abstract Properties were studied of cement mortars made with replacing 20% of ordinary Portland cement by a slag powder vitrified from an ash mixture (composed of fly-ash and scrubber-ash from a municipal solid waste incinerator, MSWl) and...

Usage of coal combustion bottom ash in concrete mixture.
September 1, 2008... Abstract The present study aims to determine and evaluate the applicability of an industrial bottom ash (CBA), supplied from Tuncbilek Power Station-Turkey, in concrete industry. In the laboratory experiments, the bottom ash was used up to...

A new composite for external reinforcement: steel cord reinforced polymer.(Table)
September 1, 2008... Abstract Today, mostly steel plates and carbon fibre reinforced polymers (CFRP) are used as external reinforcement. This paper deals with a new material that can be used as external reinforcement: steel cord reinforced polymer (SCRP). It...

Investigations on mix design of tungsten mine waste geopolymeric binder.(Table)
September 1, 2008... Abstract Strength data show that the parameters, which lead to optimum strength for 7 days curing, remain the same for long curing ages. However, when calcium hydroxide percentages above 10% are used, strength decrease after 14th curing...

Evaluation of moisture damage in hot mix asphalt using simple inperformance and superpave direct tensile tests.
September 1, 2008... Abstract Moisture damage has been one of the major concerns for hot mix asphalt (HMA) pavements. In the present study, efforts have been made to evaluate the moisture damage of a dense-graded surface HMA mixture using simple performance...

Performance of self-compacting concrete containing fly ash.
September 1, 2008... Abstract The influence of including fly ash (FA) on the properties of self-compacting concrete (SCC) is investigated. Portland cement (PC) was partially replaced with 0-80% FA. The water to binder ratio was maintained at 0.36 for all...

Effect of chemical structure of polycarboxylate-based superplasticizers on workability retention of self-compacting concrete.(Table)
September 1, 2008... Abstract In self-compacting concrete (SCC) mixture design, polycarboxylate-based superplasticizers (PC-based SPs) usually guarantee the initial workability. However, the time dependent workability of mixtures principally depends on the...

Properties of cementless mortars activated by sodium silicate.(Table)
September 1, 2008... Abstract The present paper reports the testing of 12 alkali-activated mortars and a control ordinary portland cement (OPC) mortar. The main aim is to develop cementless binder activated by sodium silicate powder. An alkali quality...

Properties of concrete mixtures containing slag cement and fly ash for use in transportation structures.
September 1, 2008... Abstract The research program was designed to supply initial data on the influence of slag cement on the fresh and hardened properties of concrete to be used in pavements and bridge structures. There were three goals in the study. The...

Experimental investigation of adhesion failure of the interface between concrete and polymer-cement mortar in an external wall tile structure under a thermal load.
September 1, 2008... Abstract This paper aims to present an experimental method for investigating an adhesion failure of the interface between concrete and adhesive mortar in an external wall tile structure under a thermal load. The laboratory-scaled heating...

Stochastic simulation of the influence of variation of mineral material grading and dose weight on the homogeneity of hot-mix asphalt.(Table)
September 1, 2008... Abstract The aim of the study is to evaluate the influence of random errors of the stochastic technological process occurring in a batch type plant on the homogeneity of the hot-mix asphalt (HMA). The article presents the algorithm of...

The influence of aggregate, filler and bitumen on asphalt mixture moisture damage.(Table)
September 1, 2008... Abstract Moisture damage in an asphalt mixture can be defined as the loss of strength, stiffness and durability due to the presence of moisture leading to adhesive failure at the binder-aggregate interface and/or cohesive failure within...
