LR Pardo & Associates engaged in a research project to investigate the correlations between FWD and LWD results. The tests were carried out in the Brimbank district in June and July 2015. The investigation aimed at determining whether or not a correlation between the LWD and FWD exists that could be used to predict the […]
(118K) ABSTRACT: Vertical moisture barriers are used to minimise the seasonal movement of pavements on expansive soil subgrades. This paper discusses the performance of two types of barriers – geomembrane and L/FA grout curtain– at two test sites in Victoria, Australia.
(312K) ABSTRACT: This paper will present the findings of various research programs and laboratory tests on the effects of slow-setting cementitious stabilisation binders on marginal pavement materials. It will present the VicRoads evaluation of the slow-setting binder developed by Blue Circle Southern Cement, Alkali-Activated Slag (commercially known as “Roadment”). The information presented includes research work performed […]
Sponsor of the Glen Eira BusEd programme To develop a system that allows easy project management, easy navigation of documents and remote access to all past and present documents.
Industry Sponsored Undergraduate Research Project Significant issues regarding coastal erosion and deposition problems were identified by LRP&A following consultation with clients. The main engineering disciplines involved are: Coastal Engineering (Civil) Coastal Planning ((Municipal) Coastal Protection (Civil / Geotechcnical/ Environmental) Modelling (flow processes – civil, mechanical, environmental) The LGAs invited to participate are: Bayside city Council, […]
(1.8M) ABSTRACT: Local government roads constitute more than 80% of the 810,000km long road network in Australia. The combination of larger vehicle loads, increased traffic flows, ageing infrastructure and adverse environmental conditions has contributed to continual degradation of many Australian roads. This paper presents results of a survey undertaken to determine the state of the road […]
(28K) ABSTRACT: In the last few years, stabilisation of pavement materials has become one of the most common methods of pavement rehabilitation. To this effect, pozzolans (such as lime and cement) have been used to enhance the engineering properties of the pavement materials. Also, ground granulated blast furnace slag (GGBFS or Slag), alkali activated slag (eg. […]
(505K) ABSTRACT: This paper looks at the new method of monitoring the effectiveness of vertical moisture barriers based on the ARRB Walking Profiler. It was found to be an accurate, relatively rapid and cost effective means of monitoring the performance of vertical moisture barriers, which are used alongside pavements to minimise the damaging effects of expansive […]
(194K) ABSTRACT: Vertical moisture barriers are used to minimise the differential movement of pavements on expansive soil subgrades. This paper discusses two types of barrier: (1) the geomembrane barrier, developed for alluvial expansive soils, and (2) the lime and fly ash grout curtain, for residual expansive soils.
