摘要： Methods are provided for predicting the properties of an asphalt fraction that contains two or more asphalt components based on measurements of the viscosity versus temperature profile for the components of the asphalt fraction. The viscosity versus temperature profile for each component can be used to determine characteristic (such as limiting) values for the viscosity and temperature for a components. Examples of characteristic values for an asphalt component are the asymptotic values of viscosity at infinite temperature (ηinf) and the finite temperature at which the viscosity diverges (T0). Once these characteristic values are determined, the characteristic values for each component can be combined in a weighted average to determine ηinf and T0 for the asphalt blend. Based on this ability to determine characteristic values for an asphalt blend based on the properties of individual blend components, appropriate blends of asphalts can be selected in order to arrive at an asphalt blend with desired properties.

摘要： Methods are provided for forming an asphalt fraction corresponding to a blend of asphalts, the asphalt fraction having at least one property that is unexpectedly better than the expected property value based on the individual asphalts used in the blend. The unexpectedly beneficial blends of asphalts are formed in part by including an effective amount of a Napo crude oil or crude fraction in the feed used to form the asphalt fraction. For some asphalt blends, including an effective amount of a Napo crude in the feed can allow for production of an asphalt with a low temperature performance grade that is lower than the predicted value by at least 0.5° C., such as at least 0.75° C. or at least 1.0° C.

摘要： Compositions including reclaimed asphalt may be optimized for performance that is comparable with asphalt compositions that do not contain any reclaimed asphalt. In a method to determine an optimal level of reclaimed asphalt for use with at least a rejuvenator, TSRST tests are carried out on test asphalt compositions with varying levels of reclaimed asphalt (RA) materials to obtain failure temperature and failure stress data for all compositions. The test results are compared to identify composition(s) with optimal amount of RA. The optimal asphalt composition containing the maximum amount of RA for comparable performance may have a failure temperature within±5% of the failure temperature of the reference composition, and a failure stress that may be equal to or greater than the failure stress of the reference composition.

摘要： An asphalt shingle coating system that includes a coater, a mixer, a viscosity gauge, a wax supply, a wax pump and a control system. The coater applies a layer of a coating asphalt mixture on an asphalt shingle substrate. The mixer mixes the coating asphalt mixture and is positioned upstream of the coater. The viscosity gauge may be positioned between the coater and the mixer, and it measures the viscosity of said coating asphalt mixture before it is delivered to the coater. The wax supply is in fluid communication with the mixer and a wax pump may deliver a volume of wax from the wax supply to the mixer, and the control system may selectively adjust the operation of the wax pump to substantially maintain a desired viscosity of said coating asphalt mixture.

摘要： The invention involves “a method to structure mineral aggregate gradation by using three control points & two curves”, including the following steps: (1) Three control points are determined according to the property of the mixtures: nominal maximum size of aggregate and its passing rate, nominal minimum size of aggregate and its passing rate, and the discontinuity point between the coarse aggregate and the fine aggregate and its passing rate. (2) The grading curves of the coarse and the fine aggregate are selected respectively with Power function model, Exponential function model and Logarithmic function model. (3) Measure the stamped density and the stamped voids in mineral aggregate, and then choose the grading of the coarse and the fine aggregate on the basis of the project need. The invention can help constitute different gradation curves in line with local materials from different areas and sources. In this way can the mineral aggregate's property give the full play to the mixtures, and it's a good guide to the mix proportion of the asphalt mixture.
