“…There are two main categories of paved roads in Malaysia, which are flexible and rigid pavements (Koting et al, 2011;Ayob et al, 2017). Rigid pavement is classified based on its concrete surfaces and bases, which implies high strength and durable characteristic that allow it to span some minor irregularities in the subgrade or sub-base of the pavement (Koting et al, 2011;Hong Kong Highways Department, 2012;Ayob et al, 2017). The basis for classification of concrete pavement types is the jointing and reinforcing system adopted.…”

Many scholars asserted that LCC plays an important role in the cost estimation of rigid pavement due to high construction, maintenance and reconstruction costs in Malaysia. Due to high budget allocation and expenditure on the maintenance and rehabilitation works of pavements in Malaysia by the government, it is crucial for the transportation agencies to optimize the budget allocation and select the most cost-effective pavement maintenance and rehabilitation alternatives. LCC is a useful economic assessment technique that compares the cost-effectiveness of different maintenance and rehabilitation approaches within the same road pavement type. However, in order to produce a comprehensive and reliable LCC output, there is need to ensure the cost data inputs is ready and quality enough to be used in the LCC estimation. This paper presents the outcomes of the comprehensive literature review on the state of cost data inputs for LCC analysis of rigid pavement maintenance and rehabilitation in Malaysia. The outcomes of the literature study have established that the majority of the construction industry key players are aware LCC analysis should be practiced in the rigid pavement maintenance and rehabilitation. However, the current state of LCC practice of rigid pavement maintenance and rehabilitation in Malaysia is still at the infancy stage and unready to be implemented due to the difficulties in attaining quality cost data for generating a comprehensive and reliable LCC analysis. The findings provide information on the current state of cost data inputs of LCC analysis of rigid pavement maintenance and rehabilitation in the Malaysian construction industry.

“…In addition, its high temperature stability and water damage resistance are superior to asphalt concrete pavement, and its shear resistance, fatigue resistance, and slip resistance are also superior to cement concrete pavement. At the same time, it has the characteristics of oil resistance, acid resistance, and easy coloring [6,7].…”

This paper aims to optimize the asphalt-mortar interface characteristics of semi-flexible pavement coating material (SFPCM), three types of the interface modifiers, namely the silane coupling agent, carboxylated styrene-butadiene latex, and cationic emulsified asphalt, are selected to add into the cement mortar to optimize the asphalt-mortar interface. The microscopic characteristics of the asphalt-mortar interface and the macroscopic pavement performance of the SFPCM after the interface optimization are investigated to reveal the effect of interface modifiers and determine the best formula. Results show that: (1) The dry shrinkage of the cement mortar is increased with the increased dosage of the interface modifiers, while the strength is decreased accordingly; (2) the optimum dosages of the silane coupling agent, carboxylated styrene butadiene latex, and cationic emulsified asphalt are 0.5%, 10%, and 5%, respectively; (3) the microscopic asphalt-mortar interface characteristics of the SFPCM with different interface modifiers have significant differences; (4) the SFPCM with the cationic emulsified asphalt presents the best pavement performance, particularly the high-temperature stability. These results can be attributed to improve the pavement properties of SFPCM.

“…Semiflexible pavement is a composite pavement made by pouring cement slurry into a porous asphalt mixture with the porosity between 20% and 28% [2]. e pavement is a new type of pavement which combines the advantages of rigid cement concrete pavement and flexible asphalt pavement [3]. e semiflexible pavements have been applied to roads, airfields, sea ports, and industrial heavy-loading yards on account of their excellent rutting resistance, fatigue resistance, abrasion resistance, oil resistance, and colorability [4].…”

Cement mortar is one of the most important components of semiflexible pavement materials; however, the effects of cement mortar formulation on the performance and the grouting rate are rarely studied. Therefore, the optimum formulation of high-performance cement mortar (HPCM) for different types and contents was studied, and the grouting effect of the cement mortar was studied by rutting tests. The results show that polycarboxylate superplasticizer, expansion admixture, and accelerating admixture have different influences on the workability, the strength, and the drying shrinkage of HPCM, and the working ability of HPCM is good by adding these three admixtures. The strength at 7 days is 1.3 to 4 times that of the existing specifications, and the shrinkage rate is less than 0.2. The HPCM has higher early strength, and the strength development is stable in the later period compared with the other research studies. The semiflexible material has better pavement performance when the grouting rate is greater than 90%.
