What is the RP1253T asphalt paver?
The RP1253T is a state-of-the-art asphalt paver designed to meet the rigorous demands of modern road construction machinery. It is designed to provide excellent performance in various environments, from scorching deserts to icy tundras.
Unique advantages of the RP1253T
1.Unprecedented Efficiency
One of the most striking characteristics of the RP1253T is its excellent efficiency. In highway construction scenarios, it has been tested to achieve a paving capacity of 600 tons per hour, a 22% increase compared to the average of similar wide-width pavers.
2.Precision engineering
In road construction machinery, accuracy is the most important, and the RP1253T has performed well in this respect. It is equipped with a triple leveling system of double lasers and millimeter-wave radar, which ensures the positioning accuracy of the National Construction Machinery Quality Supervision and Inspection Center in 2024 ≤ 0.3mm.This level of precision guarantees a smooth and even surface, enhancing the longevity and safety of the asphalt road.
3.Durability under extreme conditions
The RP1253T is built to withstand the harshest of conditions. Its engine can work in the temperature range of -45℃ to 125℃. In the laboratory test, the success rate of three starts at -45℃ is 100%. The hydraulic oil keeps the best performance between -35℃ and 85℃, ensuring that it can work continuously for 16 hours in the high temperature environment of 45℃ without trouble.
4.Energy efficient
In this era when energy saving is crucial, the RP 1253 shines with its low fuel consumption. Laboratory tests show that it only consumes 42 liters of fuel per hour, 15% less than its competitors. This not only reduces operating costs, but also minimizes the impact on the environment, which is in line with global sustainability goals.

Major application occasions
1.Large scale expressway Construction
RP1253T is mainly used in the construction of inter-provincial expressways and national trunk lines that require wide paving (10-12.5m). The main customers include central enterprises in the field of infrastructure, such as China Communications Construction and China Railway Construction, which have participated in the reconstruction and expansion of the Beijing-Shanghai and Guangzhou-Shenzhen expressways.
2.Municipal main road engineering
In urban areas, the RP1253T is used to pave wide (8-10m) pavements on urban expressways and ring roads. Typical projects include the municipal section of the Hangzhou Ring Expressway and the extension project of Tianfu Avenue in Chengdu.
3.Airfield runway project
The paver is also well-suited for constructing airport runways and cargo aprons, where high flatness and wide-width paving are essential.
Case study:
· A central enterprise in the highway construction sector faced significant challenges during a 12.5 m wide-width asphalt paving project on a cross-provincial highway. Traditional wide width machine leads to insufficient edge compaction (only 92%) and requires secondary compaction. In addition, during the high temperature operation at 45℃, the hydraulic system is shut down every 8 hours, which limits the daily paving quantity to 3000 tons, which is 40% less than the project requirement.
· The solution was to deploy two RP1253T pavers, leveraging their dual-variable distribution system to resolve edge aggregate deficiency and their three-stage cooling system to handle high temperatures.
· Edge compaction is increased to 98%, and secondary compaction is not required; Continuous operation at high temperature for 16 hours without failure; Daily paving capacity reached 5200 tons, and the project was completed 8 days in advance; And reducing construction costs (including compaction and downtime losses) by 12%, earning the client an “Excellent Project” award from the owner.
Common problems
Q 1:What should I do if the pressure of the hydraulic system is insufficient (less than 25 MPa)?
A 1:①Check the pressure valve at the oil outlet of the hydraulic pump (location: A 4VG 250 pump body side). If the valve core is stuck, remove and clean it and replace the hydraulic oil (model: L-HM 46); ②check whether the high-pressure hoses is aging with the hose with the original pressure resistance of 40 MPa (part number: XGRP-1253-001) (if it is used for more than 3 years, replace it)；③restart the equipment, idle for 15 minutes; The pressure should be raised to 30-32 MPa.
Q 2:How can I address edge aggregate segregation during 12.5 m wide-width paving?
A 2:①Increase the left spiral distributor speed from 180 r/min to 200 r/min, keeping the right at 180 r/min (adjust via the “Wide-Width Distribution” knob on the control panel); ②activate the edge vibration enhancement mode (frequency 55 Hz, amplitude 3.5 mm)；③keep the material level covering three-quarters of the helical blades.The separation should be alleviated within 10 minutes after adjustments.
Q 3:What should I do if the equipment is short of electricity at high altitudes (4500 m)?
A 3:①Enter “altitude adaptation” mode on the control panel (password: xcmg2024); The system will automatically adjust fuel injection); ②check whether there is dust accumulation in the intercooler of turbocharger, and clean the heat sink with compressed air (0.6 MPa)；③replace it with a special high-altitude air filter (part number: XGRP-1253-002) to ensure adequate air intake; After the adjustment, the power should be restored to 97% of the low altitude levels.
Q 4: When changing the paving width of the RP1253T from 12.5 m to 8 m, do I need to replace the core components?
A 4:No, not all the core components need to be replaced. Just follow the three steps:①Remove the 12.5 m edge extension sections (2 people, 1.5 hours);②install 8 m compatible liner (part number: XGRP-1253-003);③input new width parameters into the control system to calibrate the leveling system.Switching can be completed in 2.5 hours without special tools, which is suitable for multi-width construction.
Summary
RP1253T asphalt paver represents a great progress of road construction machinery, providing unparalleled efficiency, accuracy and durability. Its advanced technologies, robust design and versatility make it an ideal choice for a wide range of applications, from large-scale highway construction to municipal trunk road projects and airport runway construction.
