ASPHALT ROAD~F CING 11ACHINE
BACKGROliND OF TIIE INVENTION
Asphalt concrete is commonly usad in road construction. In an asphalt road construction, asphal-t cement and ~ravel are mixed and paved on a road and then pressed tight by a road roller. Hnwever, an asphalt road tends to become defarmed and aged, due to exposure to the weather, to affect driving safety. Therefore, an asphalt road must be regularly maintained and resurfaced. Drawbacks of the conventional method in resurfacing an asPhalt road maY
include:
1. It is expensive to resurface an asphalt road, because it consumes much time, man-power and material consuming;

BACKGROliND OF TIIE INVENTION
Asphalt concrete is commonly usad in road construction. In an asphalt road construction, asphal-t cement and ~ravel are mixed and paved on a road and then pressed tight by a road roller. Hnwever, an asphalt road tends to become defarmed and aged, due to exposure to the weather, to affect driving safety. Therefore, an asphalt road must be regularly maintained and resurfaced. Drawbacks of the conventional method in resurfacing an asPhalt road maY
include:
1. It is expensive to resurface an asphalt road, because it consumes much time, man-power and material consuming;
2. It is difficult to handle, because the old and waste asphalt pavement must be removed;
3. It obstructs traffic flow, because various road construction equipments and accessories are used an asphalt road must be blocked up when the asphalt road is to be resurfaced.
~ 3t~
It is -therefore, the main object of the present invention to provide such an asphalt road resurfacing machine which can efficiently excavalte and renovate an asphalt pavement through a continuous operation to minimize man-power, time and material cnnsumption.
Another obiect of the Present invention is to provide such an asphalt road resurfacing machine which is practical in use to sfficiently excavate and renovate an asphalt road without blocking up the road.
BRIEF DESCRIPTION OF THE DRAWINGS
Fig. 1 is a perspective view of an asphal-t road resurfacing machine embodying the present invention;
Fig~ 2 is a sectional view illustrating the operaticn of the present invention; and Fig. 3 is a schematic drawing illustrating that an asphalt road resurfacing machine of the present invention is carried by a tractor to renovate an asphalt road pETAILED DESCRIPTION OF THE PREFERRED EMBODIHENT
Turning now to the annexed drawings in detail, ~ ~ ~.3~J~3~
therein illus-trated is an asphalt road resurfacing machine embodying the prasent inventiun and generally comprised of a housing lO having set therein from the front to the back in proper sequence a heater 11 ~hich softens asPhalt pavement by heat and keeps the housing 10 ~arm, a first and a second scraper assemblies 12 and l3 having slightly curved cutting tools mounted thereon for excavating softened asphalt pavement, a third and a fourth scraper assemblies 14 and 15 having relatively more curved tools maunted thereon for smashing and mixing the excavated segments of asphalt pavement to pieces, a fifth scraper assembly 16 havinJ right angular tools mounted thereon for additionallY Dixing the asphalt Pieces, a shaving device 17 for shaving the surface of the e~cavated asphalt pavement. According to the present invention, all the excavating assemblies are generally comprised of a ravolving axle with resPective tools symmetrically mounted thereon at both sides. Further, a roller 18 is attached to the housing 10 at the back side for smoo-thing the road. The road can then be smoothed further by a road roller to become in a renovated condition.
According to the present invention, the scraper assemblies 12, 13, 14, 15 and 16 each ii respectivelY
suspended by a pair of rectangular blocks 19 fixedly set inside the housing 10 at both sides. A screw rod 20 which is driven by a hand-wheel 21 is mGunted on each rectangular block 19 and engaged wi-th one end of an scraper assembly 12, 13, 14, 15 or 16. Tbrough the control of a hand-~heel 21, the level positioning of an sCraPer assembly 12, 13, 14, 15 or 16 can be well adjusted according to the condition of the asphalt pavement to renovate. The power transmission of the present invention is made thrDugh a gear box 22 and chain wheel driving mechanism. According to tha present invention, the scraper assemblies 12, 13, 14, 15 and 16 each includes a chain wheel set comprised of two chain wheels and all the chain wheel sets of the scraper assemblies are connected by a respective chain between each tuo assemblies. The gear box 22 comprises a spindle 23 having a chain wheel 24 mounted thereon at the front end connected to the chain wheel set 25 of the first scraper assemblY 12 via a chain to further carry the second, third, four-th and fifth scraper assemblies 13, 14, 15 and 16 through respective chain wheel sets and chains.
Further, a water sprayer may be mounted nn the housing 10 at the back side above the roller 18 to smooth the rolier 18, v~gt ~
and a Pair of ~heels are mounted nn the housing bilaterally at the bottom rear end, as indicated in the dotted lines of Fig. 1, per~itting carrying of the present invention to a job-site. Upon a.rival at job-sile, the wheels are removed from the housing 10 permitting the present invention be carried by a tractor to start asPhalt pavement excavating and resurfacing process.
I~Jhen in operation, four operatcrs will be sufficient to perform asphalt pavement excavating and resurfacing Process through the present invention, i.e. one tractor driver to drive a tractor to carr~ the present invention, one operator to adjust the present invention, one road roller driver, and one road grader driver.
