HRF100B is a very high cost performance hydraulic seal paver for pavement maintenance of high-grade highways, including surfacing and slurry seal. It is equipped with advanced and robust electro-hydraulic control elements to ensure stability and advancement of control and operation as well as precise mixing ratio of slurry compound and guarantee easy and correct control of construction quality by customers.
HRF-100B is applicable to modified (micro-surfacing) slurry sealing, for which modified emulsified asphalt is made with high polymer, e.g. SBR or SBS and featured in better high temperature stability and low temperature crack resistance. It is able to improve general performance of pavement and extend life span of pavement by applying modified slurry sealing. Furthermore, it is able to open for traffic within one hour after construction, which reduces traffic control after sealing. It is applicable to preventive maintenance construction of high-grade highway pavement and urban road as well as rutting repair and mixing of cold materials.
Slurry Seal / Micro-surfacing
Stainless steel,280 liters
Belt conveyor, 24 inches wide, variable rear gate for calibration, steep hopper walls minimize bridging, automatic shut down of system when aggregate is empty. Hydraulic vibrator on hopper side.
