Temperature control pavement heating method for hot in-place recycling pavement
The invention discloses a temperature control pavement heating method for a hot in-place recycling pavement, which is characterized in that at least three heating devices are arranged in front of the hot in-place recycling pavement to be treated, a heat preservation covering device is correspondingly arranged behind each heating device, and a pavement raking device is arranged behind the last heat preservation covering device; the numerical value of the sum of the lengths of all the heating devices and the lengths of all the heat preservation covering devices is used as a numerator, the numerical values of the advancing speeds of all the heating devices, the heat preservation covering devices and the road surface raking device are used as a denominator, and the ratio of the numerator to the denominator is used as heat preservation covering time; the upper surface temperature of the hot in-place recycling pavement is controlled to be less than or equal to 190 DEG C, and the bottom surface temperature of the hot in-place recycling pavement is controlled to be greater than or equal to 85 DEG The upper surface and the bottom layer surface of the upper road surface are fully softened through circulation of heating-covering heat preservation for three times or multiple times, lossless raking of the old road surface is achieved, and the construction quality and the construction efficiency are improved.
本发明公开了一种用于就地热再生路面的控温路面加热方法，其在待处理的就地热再生路面的前方布置有至少三台加热设备，每个加热设备后方对应的布置有一保温覆盖设备，在最后一个保温覆盖设备的后方设置有一路面耙松设备；以全部加热设备的长度与全部保温覆盖设备的长度之和的数值为分子，以所有加热设备、保温覆盖设备与路面耙松设备的前进速度的数值为分母，以分子与分母的比值为保温覆盖时间；控制就地热再生路面的上表面温度≤190℃，控制就地热再生路面的底层表面温度≥85℃。通过三次或多次“加热——覆盖保温”的循环，使在上路面的上表面与底层表面都充分软化，实现了对旧路面的无损耙松，提高了施工质量与施工效率。
