Mixture Samples

Pavement failures such as fatigue, rutting, cracking, bleeding, and stripping are typical pavement deterioration. Researchers have been experimenting with pavement modification to overcome these problems. This study determines the optimum binder content (OBC) for modifying an asphalt mixture with a partial replacement of coarse aggregate (5mm-14mm sieve size) with palm kernel shell (PKS). A 60/70 penetration grade bitumen was mixed with 10, 20 and 30% PKS at selected aggregate gradation following the Public Work Department of Malaysia (JKR/SPJ/2008-S4) specification. The preparation of 60 samples of unmodified and modified asphalt mixture employed the Marshall Method compacted with 75 blows. The OBC was determined based on five volumetric properties of asphalt mixture namely stability, flow, bulk density, void filled with asphalt, and void in total mix. The OBC and volumetric properties of the modified PKS asphalt mixture samples were compared with unmodified asphalt mixture samples in accordance to the specification. Results showed that the OBC sample with 30% aggregate replacement produced the highest OBC value of 5.53% relative to the control sample with 5.40% OBC. The trend for OBC with PKS replacement begins with 10% PKS with 5.30% OBC, 20% PKS with 5.32% OBC and 30% PKS. All volumetric properties of the PKS samples are within the specification limit. Thus, PKS has a promising potential as a coarse aggregate replacement in asphalt mixture.

The Impact

Utilization of the waste products in the agricultural industry has been the focus of Research for economic, environmental, and technical reasons. Sugarcane Bagasse Ash (SCBA) is one of the promising material, with its potential proved to be used as a partial replacement of cement as well as mineral admixtures for producing concrete; properties of such concrete depend on the chemical composition, fineness, specific surface area of SCBA. An experimental investigation will be carried out to examine the impact of replacing cement by bagasse ash to the mechanical and physical properties of pastes and mortars, fresh and harden concrete such as consistency, setting time and workability, compressive strength. Sugarcane Bagasse Ash powder used by replacing fly ash at 40%, 50%, and 60%. Compressive strength and water absorption test will be carried out for evaluating the performance of the material.

This paper presents the results of investigation conducted to evaluate structural performance of lateritic concrete containing palm kernel shell (PKS) as partial replacement of coarse aggregate by weight. The properties evaluated were: workability, density, compressive strength, microstructure, sorptivity, and water absorption of lateritic concrete with PKS specimens. The coarse aggregate fraction of the lateritic concrete was partially replaced with PKS of up to 50% at interval of 10% by weight. The results showed that: (i) the use of PKS to partially replace the coarse aggregate in lateritic concrete resulted in harsh concrete with low workabilities, (ii) lateritic concrete with PKS as partial replacement of coarse aggregate of up to 50% developed densities that can be used for normal concrete application, (iii) lateritic concrete with PKS as partial replacement of coarse aggregate of up to 10% developed strength that is comparable to the specimens without PKS, (iv) the SEM images of lateritic concrete samples showed a progressively porous internal structure with PKS and (v) lateritic concrete with PKS as partial replacement of coarse aggregate results in porous material but became less porous at longer curing ages. It can be concluded from these results that the replacement of the coarse aggregate constituent with PKS by weight not exceeding 10%, in the production of lateritic concrete, resulted in a material with satisfactory structural performance.
