A laboratory study on cold-mix, cold-lay emulsion mixtures

This paper describes laboratory experiments and presents results for the performances of cold-mix, cold-lay emulsion mixtures. The main objective of the experiments was to evaluate and improve the properties of the cold mixtures. The mixture properties evaluated were: volumetric properties, indirect tensile stiffness modulus (ITSM), repeated load axial creep and fatigue. These properties were compared with conventional hot asphalt mixtures not containing any waste/recycled materials. To optimise the performances of the mixtures, a target of ITSM value of 2000 MPa was selected. At full curing conditions, the stiffness of the cold mixes was found to be very similar to that of hot mixtures of the same penetration grade base bitumen (100 pen). Test results also show that the addition of 1–2% cement significantly improved the mechanical performance of the mixes and significantly accelerated their strength gain. The fatigue behaviour of the cold mixes that incorporated cement was comparable with that of the hot mixtures

Production Stage and Risk Identification on Asphalt Mixing Plant in Bali

Cost, quality and time are an important performance indicators in the project success. To achieve these objectives various risks are faced in each project life cycle. One of these risks is supply chain risk, which must be managed properly, doe to the uncertainty in this activity. There are still many companies that do not understand the importance of supply chains, so they often become obstacles in achieving project goals This study aims to identify risk factors in each stage of supply chain activities, in road infrastructure in Bali Province. Data were collected from questionnaire survey, interviews and focus group discussion from 15 units asphalt mixing plant supplier in Bali, who understand supply chain issues, especially in road infrastructure work in the province of Bali. The results of research on risk is firstly AMP production processes identified as a field of manufacturing industry that produces hot asphalt used in infrastructure projects in Bali. This research was conducted at the AMP unit found in Bali. From research, the production process and AMP business are based on Supply, Input, Process, Output and Customer activities. (SIPOC). After the activities contained in the Asphalt production process, it is known that further risks can be identified. Second identity the risk on SIPOC process
