With reference to Fig. 3 to Fig. 5, substrate 110 can have the shape of rectangular flat, and in this case, substrate 110 can have suitable length, width and thickness. But, the shape of substrate 110 is not limited to rectangular flat, and substrate 110 can have any suitable shape. Substrate 110 can have the shape of square plate.
First first type surface 111 of substrate 110 can be the front of substrate 110, and the second first type surface 112 can be the back side of substrate 110. First first type surface 111 of substrate 110 and the second first type surface 112 may each be smooth surface, and can be parallel to each other.
First first type surface 111 of substrate 110 can have for guiding patch seam glue 150 to attach at least one guide line 111a on test board 120. With reference to Fig. 8, when when being shaped as rectangle of substrate 110, guide line 111a can include by two diagonal connected along non-conterminous two angles of substrate 110 periphery of substrate 110, through the horizontal line of two cornerwise intersection points and the longitudinal direction being perpendicular to substrate 110 with through two cornerwise intersection points and the horizontal ordinate being perpendicular to substrate 110. Owing to the first first type surface 111 of substrate 110 having at least one guide line 111a, enabling guide patch seam glue 150 to attach correct position on test board 120. To be specifically described how guide line 111a guides patch seam glue 150 to attach on test board 120 below.
Test board 120 can have the shape of rectangular flat, and in this case, test board 120 can have suitable length, width and thickness. But, the shape of test board 120 is not limited to rectangular flat, and test board 120 can have any suitable shape.

Test board 120 can be discharged from substrate 110 according to contrary operation. Therefore, test board 120 is removably joined to substrate 110.
In one exemplary embodiment, with reference to Fig. 8 and Fig. 9, the first first type surface 111 of substrate 110 may be configured to hold at least one of groove 113 of test board 120, so that test board 120 is removably joined to this groove 113.
This groove 113 can have the shape and size identical with the shape and size of test board 120, so that when test board 120 is joined to this groove 113, the first recessed first type surface 111 of the basal surface contact substrate 110 of test board 120 is also supported by the first recessed first type surface 111 of substrate 110, being partially in same level except groove 113 of the top surface of test board 120 and the first first type surface 111 of substrate 110.
In addition, because groove 113 can have the shape and size identical with the shape and size of test board 120, so when test board 120 is joined to this groove 113, the sidewall of groove 113 closely contacts with the side surface of test board 120 so that test board 120 is stably fixed in groove 113.
Although described above is being partially in same level except groove 113 of the top surface of test board 120 and the first first type surface 111 of substrate 110, but the invention is not restricted to this. The top surface of test board 120 can be higher than the part except groove 113 of the first first type surface 111 of substrate 110.
With reference to Fig. 8, the shape of this groove 113 can be rectangle, and can forming the location roughly halfway up at substrate 110, specifically, two the cornerwise intersection points connecting its non-conterminous two angles of groove 113 can overlap with the two of guide line 111a cornerwise intersection points. Additionally, the longitudinal direction of groove 113 can be parallel to the longitudinal direction of substrate 110, the transverse direction of groove 113 can be parallel to the transverse direction of substrate 110.
Additionally, the basal surface of groove 113 can be coarse, so that the motion that test board 120 is in groove 113 is hindered.
First first type surface 111 of substrate 110 edge in the outside of groove 113 and close groove 113 could be formed with multiple screwed hole 114.
Screwed hole 114 is arranged in the periphery of groove 113 dispersedly. With reference to Fig. 8, although provide 4 screwed holes, and screwed hole is substantially distributed in 4 adjacent corner of rectangular recess. But the present invention is not limited to this. Such as, the quantity of screwed hole can be 2,3,5 or 6, and respectively along the periphery of groove 113, for instance, 2 screwed holes are arranged in the position at substantially 1/2 place of the length of rectangular recess side.
Test suite 100 according to the present invention may also include the fixed part 130 of the groove 113 for test board 120 is fixed to substrate 110. With reference to Fig. 6 and Figure 10, fixed part 130 can include the securing member 131 that matches with the screwed hole 114 formed on the first first type surface 111 of substrate 110 and for pressing the catch 132 of the marginal portion of test board 120.

Therefore, test board 120 is fixed in the groove 113 of substrate 110. Test board 120 can be discharged from the groove 113 of substrate 110 according to contrary operation. Therefore, test board 120 is removably joined to substrate 110.
Test suite 100 according to the present invention may also include the support portion 140 on the second first type surface 112 (that is, the back side of substrate 110) being fixed on substrate 110, to support substrate 110.

First alar part and the second alar part can have the form of rectangular flat, but the invention is not restricted to this. Base, the first alar part and the second alar part can be shaped as one.
In order to support substrate 110 better, in the outer surface of the first alar part of U-shaped supporter or the outer surface of the second alar part can be generally aligned in the same plane with the side surface of substrate 110.
Because support portion 140 can include four U-shaped supporters, and each U-shaped supporter is respectively provided with inner chamber, so that the weight of test suite 100 is unlikely to weigh very much.
Although described above is support portion 140 can include multiple U-shaped supporter 141,142,143 and 144, but the invention is not restricted to this. Support portion 140 can be any suitable support portion, as long as it can bear the pressure applied when performing road performance test. Such as, support portion can include solid multiple pillar support bodies, be formed the platform shape supporter of one, etc.
