As for the half-cylinder specimen, it is impossible to accurately predict the target strength of splitting flexural strength, but the main purpose of the test is to explore the influence of micro-structural evolution on the performance of porous asphalt mixture, so the modified asphalt mixture flexural strength test can be used to evaluate the splitting shear strength of porous asphalt mixture. The modified bending-tensile test is to place half of the cut Marshall specimen on the test machine, press the semicircle arc of the specimen on the upper side, press the cutting surface of the specimen on the lower side, and then load the mixture for bending-tensile strength test (Li and Marasteanu 2010) (as shown in Figure 17). The test temperature was 20°C and the loading rate was 50 mm/min. The split flexural strength RB of porous asphalt mixture is calculated according to Equation (3). The tensile strength R, the maximum bending strain ϵB of the beam bottom and the bending stiffness modulus SB were calculated. where RB is the refers to the flexural tensile strength of the specimen under failure(MPa); B is the width of the intermission piece(mm); his the height of the intermission piece (mm); L is the span of the specimen (mm); PB is the maximum load when the specimen fails(N) and d is the mid-span deflection (mm) in case of time failure.

Different techniques are used to extract oil from the feedstock, in the traditional method, in which a machine press is operated manually, can produce up to 3–4 litres of oil from 10 to 12 kg of seeds. Other techniques, such as oil ejectors and automatic machine presses, are often used for large-scale extraction of oil. The chemicals, such as enzyme treatments and soxhlet extraction, are used for batch scale extraction of oil (De Oliveira, Davantel De Barros, and Gimenes 2013; Bulley et al. 1984).
