Abstract: The construction procurement evaluation method using lowest price conforming methods often causes some quality problems for  owners and increases the probability of dispute and delay during the contract execution. On the other hand, merit point system evaluation method can provide quality assurance, but the procurement committees are often dificult to apply it, and to determaine mesurable criteria evaluation.Therefore, it is necessary for a more in-depth study to find out the criteria evaluation for construction procurement. The research conducted in Bali, and adopted inductive qualitative approach involving 45 experts participated in construction procurements using merit point system evaluation.Puposive sampling is applied to determine the respondents come from all actors included during procurement process. The data was collected through interviews, observation participant and questionnaires, and the Analytic Hierarchy Process (AHP) is choosed to analyse them. The result shows that : the merit point system evaluation for construction procurement can determine the contractor provides better quality than the lowest price conforming method when theevaluation criteria are clear, mesurable and transparant in the bidding document. There are two principle aspects that must be considered to assurethe quality that is: the technical aspect and the cost that weight consecutively 60% and 40%. The technical aspect comprises of : a) the existance of work plan (13.51%), comprising of construction methods (4.12%), supporting  equipment (4.05%), supporting material (3.46%), suporting workers (1.88%); b) competencies of human recources (19.91%), comprising of project management competencies(2.31%), existence of expert (7.92%) and certificated human resources (9.68%); c) existence of supporting equipments (15.54%) consisted of lifting support (4.79%), transportation support (6.17%), surveying support equipment(4.58%); d) the existing of time management (6.30%) consisted of network planning (4.13%), bar chart (1.03%), and S-curve (1.14%); and e) existence of quality assurance (2.14%) consisted of quality management system (1.95%), performance quality management (0.66%) and material management quality (2.14%). From price point of view, it must be evaluated the faireness of price and price offer that weighs consecutively 25.66% and 14.34%.

This paper aims to explore the reasonability of an evaluation method on high temperature performance of asphalt mixture through a series of experiements. The first step of these experiements is to formulate specimens of different high-temperature performances by Gyratory Testing Machine which simulates the on-road pavement to the most extent , and then adopt triaxial dynamic compression test to compare and analyze high-temperature performances of these specimens. By introducing concepts and indicators such as validity, reliability, discrimination, this paper evaluates comprehensively the discrimination results of various compression test parameters on high-temperature performance of asphalt mixture. It concludes that the evaluation effect of compression stiffness modulus is best, followed by the slope of logarithmic creep curve and accumulated strain area, and the evaluation effect of final compression strain is comparatively poor. That provides an objective evaluation method on high temperature performances of asphalt mixtures.

Usually, foamed asphalt as cold recycling mixture binder, study on foamed asphalt warm mix technology was limited in China. Aimed at the asphalt foaming characteristic, the paper put forward the best asphalt foaming condition and carried out indoor and outdoor experiment to study the road performance of warm mixed asphalt mixture. The paper proposed the maturation curing time concept and its evaluation method. Results indicated that the warm mixed asphalt mixtures road performance can meet the HMA specification requirement in a lower temperature of construction, and low-temperature crack resistance was better than the tradition hot mix asphalt mixture so the warm mix foamed mixture has a remarkable economic and society benefit.
