Bitumen penetration grade 40/50 bitumen means the penetration value is in the range 40 to 50 at standard test conditions which commonly used as a Paving Grade. Bitumen is applicable for the production of hot mix asphalt for bases and pavements and for road construction. Penetration Grade Bitumen supplied by RABIT (RAHA BITUMEN) Co. This bitumen is produced through aeration on vacuum bottom (the raw material used for making bitumen left in vacuum distillation column in oil refineries) in bitumen production units. Its penetration grade ( the measure of bitumen hardness) is between 40 to 50. Bitumen is specified by the penetration and softening point test. Designing is by penetration range only. The penetration grade bitumen has a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature-viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability and application temperatures of bitumen.
Bitumen Penetration Grade 85/100 is a standard penetration grade Bitumen usually used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties. This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Penetration Grade Bitumen supplied by RABIT (RAHA BITUMEN) Co. is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil. The Bitumen supplied by RABIT Trading Co. This bitumen is produced through aeration on vacuum bottom (the raw material used for making bitumen left in vacuum distillation column in oil refineries) in bitumen production units. Its penetration grade ( the measure of bitumen hardness) is between 85 to 100. Penetration Grade bitumens are specified by the penetration and softening point test. The designation is by penetration range only. The penetration grade bitumens have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/ viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability and application temperatures of bitumen. The Bitumen mode is dependent on temperature. The temperature-vs-stiffness relationship of bitumen is dependent on the type of crude oil and its refining method. Bitumen penetration grade 85/100 is semi hard penetration grade bitumen used as a paving grade bitumen which is suitable for road construction and repair. It is also used for the production of asphalt pavements with the below technical specification. This grade of bitumen is mainly used in the manufacturing of hot mix asphalt for bases and wearing courses. Bitumen 85/100 is one of the most used bitumen grades and it�¢??s a basic material for all other bituminous products. Penetration determines the hardness of bitumen by measuring the depth to which a standard loaded the needle will vertically penetrate in 5 seconds, in a sample of bitumen maintained at a temperature of 25 degrees Celsius.

Here are the specifications of the new version: * The program works with the Audio Analyser ATB 701 * The program includes the comfortable ATB 701QC program * Setting of the definition without script, there is no need of learning to program * Tolerance field is easy to set automatically or with the mouse * Rub&Buss is tested with the signal 13 to get a nonlinear distortion measurement * Surrounded noise does not disturb the Rub&Buss measurement because of the Q-Index calculation Measurement functions 1. Total Harmonic Distortion THD 2. Intermodulation Distortion, IMD 3. Frequency response(SPL) 4. Impedance(IMP) 5. Polarity Test 6. Thiele-Small Parameter 7. Phase 8. Step response 9. Quality Control Program Thiele-Small Parameter Frequency response of phase Intermodulation Distortion IMD Total Harmonic Distortion THD Quality Control Program Rub&Buss measurement Passed Rub&Buss measurement Failed 1. Frequency response The frequency response is tested with the M-PN signal. The measurement with this periodic noise gives the highest accuracy. The tolerance mask can be set automatically or manually. 2. Rub&Buss measurement The Rub&Buss is tested with the signal 13. The signal 13 consists of two sine-sweeps with the frequency ratio of 1 : 1.3. This signal is showing all resonances of the unit under test. For the passed and failed decision the Q-Index is calculated. The index is calculated from all frequencies higher than the second frequency of the test signal 13. The account is set into proportion to the amplitude of the test signal. The best speaker has the highest Q-index. The Rub&Buss measurement has following tests. Calculation of error 1. THD, K2,K10 The test is for the controlling of the placement of the voice coil. 2. IMD The test is for the controlling the gluing, loose particle and if there are cone touching of connection wires. 3. Frequencies > K5 The test is for the controlling of voice coil rubbing the magnet. 3. Distortion THD Test The THD test tests the harmonic distortion. The test signal is a sine wave with frequency to select. Because this test is included in the Rub&Buss test it is only for the special demand of the manufacturer. In the definition there is to set the maximum THD and the frequency. 4. Polarity Test The polarity test is for testing the wiring. It is for speakers, headphones and microphones. The test signal is a half sine wave. In the time response the program calculates if the positive or negative amplitude is the greatest value.
