The minimum diameter and maximum spacing of steel fabric for reinforced concrete pavement shall comply with the provisions of the current industry standard code for design of highway cement concrete pavement jtgd40. When cold-rolled ribbed steel bars are used, the diameter of steel bars shall not be less than 8 mm, the spacing between longitudinal steel bars shall not be more than 200 mm, and the spacing between transverse steel bars shall not be more than 300 mm. The longitudinal and transverse steel bars of welded mesh shall be the same diameter, and the thickness of protective layer of steel bars shall not be less than 50 mm. The welded mesh used for reinforcement of reinforced concrete pavement can be implemented according to the relevant provisions of welded mesh used for reinforced concrete pavement.

混凝土路面與固定構(gòu)造物相銜接的脹縫無法設(shè)置傳力桿時(shí)，可在毗鄰構(gòu)造物的板端部內(nèi)配置雙層鋼筋網(wǎng)；或在長度約為6一10倍板厚的范圍內(nèi)逐漸將板厚增加20%.混凝土路面與橋梁相接，橋頭設(shè)有搭板時(shí)，應(yīng)在搭板與混凝土面層板之間設(shè)置長6一10mm的鋼筋混凝土面層過渡板。當(dāng)橋梁為斜交時(shí)，鋼筋混凝土板的銳角部分應(yīng)采用鋼筋網(wǎng)補(bǔ)強(qiáng)。

When the expansion joint connecting the concrete pavement and the fixed structure cannot be provided with a dowel bar, a double-layer steel mesh can be arranged in the end of the slab adjacent to the structure; or the slab thickness can be gradually increased by 20% within the range of about 6-10 times of the slab thickness. When the concrete pavement is connected with the bridge and the bridge head is provided with an approach slab, a 6-10 mm long reinforced concrete surface layer shall be set between the approach slab and the concrete surface slab to pass through Cross board. When the bridge is skew, the sharp corner of the reinforced concrete slab shall be reinforced with steel mesh.

混凝土面層下有箱形構(gòu)造物橫向穿越，其頂面面層底面的距離小于400mm或嵌入基層時(shí)，在構(gòu)造物頂寬及兩側(cè)，混凝土面層內(nèi)應(yīng)布設(shè)雙層鋼筋網(wǎng)，上下層鋼筋網(wǎng)各距面層頂面和底面1/4一1/3厚度處。

There is a box structure crossing under the concrete surface. When the distance between the top surface and the bottom surface of the surface is less than 400mm or embedded in the base layer, the double-layer reinforcing mesh shall be set in the concrete surface layer at the top width and both sides of the structure, and each of the upper and lower reinforcing mesh shall be 1 / 4-1 / 3 thick from the top and bottom surface of the surface layer.

混凝土面層下有圓形管狀構(gòu)造物橫向穿越，其頂面面層底面的距離小于1200mm時(shí)，在構(gòu)造物兩側(cè)，混凝土面層內(nèi)應(yīng)布設(shè)單層鋼筋網(wǎng)，鋼筋網(wǎng)設(shè)在距面層頂面1/4一1/3厚度處。

There is a circular tubular structure crossing under the concrete surface. When the distance between the top surface and the bottom surface of the surface is less than 1200mm, a single layer of reinforcing mesh shall be arranged in the concrete surface on both sides of the structure. The reinforcing mesh shall be set at the place 1 / 4-1 / 3 of the thickness from the top surface of the surface.
