Abstract. Local road pavements are often comprised of thin marginal granu-lar material base courses with a thin bituminous surface. When these pave-ments require rehabilitation, new granular reconstruction is the standard historical approach. However, in recent times, stabilisation of the existing pavement has also become popular. This research calculated seven structur-ally equivalent...
Abstract. Merimbula airport is typical of regional airports in Australia, with a modest aircraft pavement network comprised of local natural gravel and a thin bituminous surface. The airport pavements were expanded and rehabilitated for larger aircraft in 2022 and this paper presents a case study of that work as an example of sustainable and resilient airport pavement re-habilitation. Novel...
Abstract. Early rehabilitation is considered an ideal strategy for managing road pavements, as it is expected to ensure longer durability to minimize the life-cycle cost. However, such a practice has not much been adopted, so its effectiveness is even difficult to understand. As a step toward imple-mentation, how many years rehabilitated pavement have so far sustained was investigated, using...
Abstract: This study provides a comparative environmental assessment of two pavement rehabilitation strategies: Full-Depth Reclamation (FDR) and Mill and Fill (M&F). The analysis includes two FDR treatments, each containing bitumen emulsion in combination with a distinct hydraulic binder (active filler). Life Cycle Assessment (LCA) methodology principles are applied to quantitatively assess...
Abstract. This study examines the changes in friction and texture following the applica-tion of shotblasting to an asphalt pavement. The primary aim is to assess both the immedi-ate impact and the lasting effects of the treatment. To achieve this, a road segment featuring an asphalt surface in optimal condition was selected. The segment was then divided into two sections: one treated with...
Abstract. Diamond grinding is a process that involves removing a thin layer of the pavement’s surface using closely spaced diamond saw blades stacked on a machine driven shaft. The level surface is achieved by running the blade assembly at a predetermined level across the pavement surface, which produces saw cut grooves. The uncut concrete between each saw cut breaks off more or less at a...
