5.9.43 MOISTURE CONTENT OF ASPHALT MIXTURES OR MINERAL AGGREGATES MICROWAVE OVEN METHOD (Kansas Test Method KT-43) 1. SCOPE This method describes a procedure for determining the amount of moisture present in asphalt mixtures or graded mineral aggregates used in asphalt mixtures. Use of this method is limited to asphalt mixtures
Jan 01, 2015 · Standard Method of Test for Moisture Content of Hot Mix Asphalt (HMA) by Oven Method This method is intended for the determination of moisture content of hot mix asphalt (HMA) by drying in an oven. The values stated in SI units are to be regarded as the standard. ASTM D1461 - 17 Standard Test Method for Moisture or 1.1 This test method covers the determination, by direct measurement, of moisture or volatile fractions of the asphalt in asphalt mixtures. 1.2 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.3 The text of this standard references notes and footnotes which provide
6.2.4 Verify that the mixture contains no more than 0.2% of moisture by weight in accordance with Tex-212-F, Part II. Do not use the same sample used for moisture determination as used for asphalt content determination. Refer to Table 1 for required sample weights.

Asphalt mixture samples must be heated and dried to determine moisture content in the mix as part of the quality control process during road construction and repair. Asphalt samples are heated to a temperature of 163°C ±14°C (325°F ±25°F), dried and tested.
mixture that may contain moisture. If the sample consists of rock asphalt, dry to constant weight at a minimum temperature of 60 C (140 F). Constant weight is the weight at which further oven drying does not alter the weight by more than 0.05% in a 2-hour or longer drying interval in Determining Moisture (Water) or Volatile Distillates 1.1 This procedure covers two methods for the quantitative determination of moisture in Hot Mixture Asphalt (HMA). 1.2 The procedures are intended for the determination of moisture content or volatile fraction of the bitumen, in HMA. 1.3 The water content of a mixture is defined by this Standard as the ratio, eed as a percentage
12.2.2 If using it for moisture correction applied to the asphalt content, then determine wet weight (mass) A at the same time the asphalt content sample is done, i.e., during ignition oven asphalt content test. 13. PROCEDURE 13.1 Place the specimen Measuring Moisture in Asphalt MixturesIn reality, the actual moisture content of that mix could be much, much higher--up to 0.7 percent, or more. Moisture remaining inside the aggregates obviously affects the amount of binder material that can be absorbed into the internal pores of those coarse and fine aggregate particles.
The importance of accurate moisture measurement and control. By David Serra, international sales manager with Hydronix Ltd. When a panel of industry quality-control experts was asked what automated measurements would add value to asphalt production, moisture content on belts/in bins and automatic gradation and moisture measurement from belt sampling came in the top three.

- BackgroundTest DescriptionResultsASTM D6307 - 19 Standard Test Method for Asphalt Content 1. Scope. 1.1 This test method covers the determination of asphalt content of asphalt mixture and asphalt pavement samples by removing the asphalt cement in an ignition furnace. The means of sample heating may be the convection method or direct irradiation method. Note 1:Aggregate obtained by this test method may be used for sieve analysis.
1.1 This test covers the determination of asphalt content of bituminous paving mixtures by ignition of the asphalt cement at 1,000EF [ 538EC] in a furnace. The asphalt in a sample of bituminous paving material is burned by ignition at 1,000EF [538EC] .

In this case, an oven should be used. Oven The most common heat source is an oven set at 230 ± 9°F (110 ± 5°C). An oven is a good choice when time is not of the essence. Samples dried in the oven, depending on the type of container used and the moisture content of the sample, may take anywhere from one to several The healing properties of asphalt mixtures suffered Nov 30, 2016 · The heating speed of asphalt mixtures was enhanced at the presence of water. Heating could only heal moisture damaged asphalt mixtures to a very limited content. The presence of moisture significantly decreased the healing rate of asphalt mixtures. The moisture on crack surfaces prevents the thermal healing of cracks.
