摘要： An apparatus and method for quickly drying porous materials. A sealable chamber is connected to a cold trap which is connected to a vacuum pump. A sample is placed inside the sealable chamber. The vacuum pump is turned on and air is evacuated through the cold trap to the vacuum pump. An infrared lamp may be used to heat the chamber and sample therein directly or heated air may be allowed to enter the sealable chamber. Air may be drawn directly from the sealable chamber to the vacuum pump bypassing the cold trap. Various parameters may be used to determine if the drying process is complete, including the degree of vacuum achieved in the chamber.

摘要： An apparatus and method for quickly drying porous materials. A sealable chamber is connected to a cold trap which is connected to a vacuum pump. A sample is placed inside the sealable chamber. The vacuum pump is turned on and air is evacuated through the cold trap to the vacuum pump. Because evaporation may lower the temperature inside the sealable chamber, an infrared lamp may be used to heat the chamber and sample therein directly or heated air may be allowed to enter the sealable chamber in response to the vacuum created by the vacuum pump. Air may be drawn directly from the sealable chamber to the vacuum pump bypassing the cold trap. A load cell may be placed in the bottom of the sealable chamber to monitor the weight of a sample to determine if the drying process is complete. Other parameters could be used, including the degree of vacuum achieved in the chamber. The cold trap extracts moisture from the system, which eliminates the possibility of damage to the vacuum and creates an added pressure gradient for removal of air from the sealable chamber. Heating the chamber either by introducing heated air or by direct use of infrared heat facilitates drying of the sample and shortens the drying process.

摘要： An apparatus and method for determination of susceptibility of asphalt concrete materials to moisture damage. An asphalt sample of known bulk specific gravity (density) is placed inside a chamber filled with water, which is capable of heating the sample to a pre-determined temperature. The chamber is pressurized by introduction of air pressure to a flexible membrane that decreases the volume within a chamber containing the sample and water, increasing the pore pressure in the sample. The pressure is then released and allowed to come to ambient pressure. This process is repeated a predetermined number of times (cycles). When a selected number of cycles are complete, the asphalt sample is removed from the chamber and its bulk specific gravity (density) measured again. The difference between the density before and after conditioning is an excellent method of rating the degree at which moisture would deteriorate asphalt samples due to introduction of moisture. The cyclic nature of the increased/decreased pore pressure is observed to significantly decrease bulk specific gravity (density) for poor quality asphalt designs. Furthermore, the sample conditioned by this method can be used for other conventional mechanical test methods, such as tensile strength and modulus determination. Computerized controls are used to automate the procedure and to record and display data from sensors.

摘要： Methods, systems, and computer program products analyze asphalt samples for anti-stripping agents by: obtaining a sample comprising asphalt binder material; sensing a selected parameter associated with the sample (such as the acidity and/or alkalinity of the sample); and analyzing the sensed parameter to assess at least one of: (a) the presence of at least one anti-stripping agent in the sample; and (b) the level of at least one anti-stripping agent in the sample. The sample can be heated so that it emits exhaust gas and the exhaust gas (directly or indirectly) interrogated to determine its pH, or other constituents or properties, such as ammonia. Pre-defined mathematical relationships can be used to correlate the measured sensed data to the concentrations of the anti-stripping agent(s) in the sample undergoing analysis. The evaluation can be carried out in a generally automated rapid manner so that the test can be completed in about 10 minutes or less. Related devices and kits are also described.
