compacted low strength material (clsm) made with material such as fly ash and recycled aggregates is used as filler at city infrastructure canals without compaction need. experimental small specimens and large canals were casted with this concrete and tested to give several results. test results of compression strengths on 12 different designs shows that this concrete with high workability and ...

Asphalt modification/reinforcement has received considerable attention as viable solutions to enhance flexible pavement performance. This is mainly prompted by the unsatisfactory performance of traditional road materials exposed to dramatic increases and changes in traffic patterns. This paper presents the evaluation of fatigue behaviour of nano reinforced Stone Mastic Asphalt mixtures. Fatigue...

A 48-year-old-woman was struck dead by lightning on October 24, 2010, in Pretoria, South Africa. The cause of death was due to direct lightning strike. Examination showed secondary missile injury on her legs. This secondary missile (shrapnel) injury was caused by the lightning striking the concrete pavement next to her. Small pieces of concrete were located embedded within the shrapnel wounds. ...

Since it is a design criteria for road drainage and sewer systems, the infiltration performance of permeable concrete block pavement (CBP) is of important significance during the service life of a road construction. Due to the entrainment of mineral and organic fines into the pores of porous concrete blocks or into the aggregates used in joints or openings, the irreversible reduction of water p...

rutting in asphalt concrete is a very common form of distress in asphalt concrete pavement which unfortunately has been incurable to date. one of the prime reasons of rutting is attributed to the behaviour of asphalt binder at elevated temperature. this study has investigated the performance of polypropylene fibres modified asphalt concrete mix against rutting. two types of asphalt concrete sam...

This article is dedicated to the development of a joint filler for cracks in asphalt concrete pavement, as well expansion joints cement pavement. The presents choice unified units and unit being developed pavement Some methods calculating main parameters created are presented. In addition, suitable prototype filler, were selected from several types.

Abstract Roads play an important role as a connection between locations and can facilitate the efficient mobility of people's economic activities. Five tests are involved in evaluating porous concrete, such slump test, compressive strength permeability flexure load capacity test (loading test). Meanwhile, there three types soil: peat, clay, hard. The measured average 24.17-27.36 MPa. According ...
